John Green, author of The Fault in Our Stars, recently told The Hollywood Reporter that he was "very reluctant" to sell the movie rights to his book, for fear of what Hollywood might do to his beloved characters. Green thinks many teen movies display a certain "datedness," and that studios tend to make them look "more like a John Hughes movie" than real life.

"Hollywood doesn't treat teenagers as intelligent as they are," Green continued. "And then when Hollywood does make a movie that kind of acknowledges the complexity and intelligence of teenagers, it does really well."He ultimately decided his novel was in good hands after the production company assured him that certain important plot points would remain the same. "Stuff that was important to me — like that Hazel have her [breathing tube] in, that it not be sentimental or exploitative, that it would be inclusive of people living with illness — they were just completely on the same page," Green said.

The production company apparently kept its promise. A new trailer for TFIOS was released earlier this week, and it features tons of dialogue pulled word-for-word from the book, among other specific details. Now if only the movie would come out already.
